Not that we've heard ANYTHING from IBM on this topic, but that's not the point of this post...

The HTTP/2 protocol is rapidly being developed and accepted.

The standardization effort comes as an answer to the rise of SPDY, an HTTP compatible protocol launched by Google[3] and supported in Chrome, Opera, Firefox, Internet Explorer 11 and Amazon Silk browsers.

As paying customers of a pretty expensive product, I think we have a fair expectation that we see HTTP/2 support in Domino on the roadmap across all platforms, just as we expect TLS 1.3 and SHA-2+ across all protocols on all platforms.

Update:

I have completed the creation of Software Problem Report #ITDL9PMP32 (APAR #LO82258) reporting the issue to the Domino Development team. ....I have created Software Problem Report asking that the product be enhanced to do this in a future release.
